To all whom it may concern:

Be it known that I, GEORGE C. VrDn'r To, a

citizen of the United States, residing at Pittsburgh, in the county ofAllegheny and State of Pennsylvania, have invent-ed oer-- ,tainnew anduseful Improvement in Con a portable truck having a receiving conveyor,adapted to be set at various angles or degrees of incline and todischarge the load from its outer end, and a loading drum so connected,with the-conveyorv truck and with relation to the conveyor as to removethe material from its position in the pile or bank to theconveyor,together with suitable driving mechanism and various other features'ofconstruction and operation, as

shall be more fully hereinafter described.

Referring to the drawings, illustrating one preferredembodiment of theinvention,

Fig. 1 is a view in side elevation of the entire apparatus in positionfor operation;

Fig. 2 is a plan view of Fig. 1;

Fig. 3 is a view in elevation from the innor end; and

'Fig. 4 is a transverse sectional View on the line TV--TV of Fig. 1.

The main framework of the apparatus, comprising the supporting truck forthe conveyor, is built of suitable structural material having the mainside beam members 22 of channel or other suitable shape, with endframing 3. The main truck is supported upon a pair of driven wheels 4=land front dirigible wheels5-5. The rear portion of the machine,comprising the removing wheel portion, is carried by a supplementalsupporting frame 6 composed of two side bars similar to bars 2, and eachis pivoted by cross shaft 7 in the brackets 8 and}? respectively of thetwo main frames. The purpose of such mounting is that the rear frameworkcarrying the removing drum may be adjusted vertically with rela-Specification of Letters Patent.

tion to the main conveyor frame, to adapt it to inequalities in theground surface, the pile of material being acted upon, or otherconditions.

Extending upwardly and rearwardly from the main frame 2 are the posts10-10 connected by stay rods 11 to the main side bars 2 and providedwith a transverse shaft 12 and sheaves 13 thereon for the lifting Saidcables are connected at each side of the supplemental frame 6, as at 15,pass upwardly over sheaves 13, and then downwardly and around thewinding drum 16 of shaft 17 having the ratchet controlled windin gearing18 of well known construction, w ereby the drum frame maybe raised andheld at any desired position or elevation, or may be lowered below thenormal horizontal level, as required.

The digging or removin drum .or wheel, which is the initial active eement of the a paratus, is mounted upon a transverse shaft 19 in therear end portion of frame 6, and is pockets similar to the usual pocketsof an ordinary bucket conveyor.

The edges 21 may be merely continuous terminals of the metal of thebuckets, as in operation. on ordinary loose material, as sand, etc, butwhere it is desirable to opcrate upon coarser material, as heavy gravel,lump coal, or similar material, I prefer to provide at one or morelocations around the periphery of the drum, as for instance, along eachalternate edge of the bucket series, a series of projecting teeth orpoints 23 secured by their inner terminals 24 to the edge of the sheetmetal, as will be readily understood. lln such case, the teeth willoperate to cut through coarser material, segregating and loosening it,rendering it possible for the plain edge buckets to scoop and elevate itand carry it around for deposit upon the receiving end of the conveyorA.

Said conveyor may be of any suitable construction, as a belt 25 passingaround an inner driving drum 26 and an outer drum 27 mounted inadjustable journal boxes 28, carried in framework 29 of the conveyor,the inner end of which is pivotally mounted on transverse shaft 7, andcapable of vertical adjustment. Conveyor belt 25 is supported in anysuitable way, as by a series of upper and lower transverse rollers 30-3lof well known construction.

Lifting post 32, bearing upon the under side of the conveyor frame byone or more rollers, is mounted upon the end framing portion of the maintruck 2 having the guiding housing 34 and a lifting'cable engaging aterminal sheave 36, and provided with. a winding drum 37 and suitableratchet controlled gearing 38, whereby the elevator A may be located atany desired inclination for delivery from its outer end.

Ordinarily, the conveyor A and the removing drum, generally designatedby the letter B, are operated together, by means of sprocket gearing 39and ll), utilizing the usual sprocket chains and wheels, whereby totransmit movement from the shaft etl thereto. Said shaft 41 is driven bysprocket gearing a2 utilizing the usual chains and wheels, from shaftl3, which is driven through gearing l-l from a motor or other primemover Clutch mechanism 46, operated by lovers 4? and i8, is adapted totransmit driving motion in the desired direction to traction wheels 4through gearing L9 and 50 of each traction wheel. whereby to propel theapparatus forwardly or bz'iclnvardly. A clutch 51 between the oppositelydriven bevel gears 5252 of shaft 43 and operated by lever 53, providesfor reversing the direction of shaft i1, it being understood that clutch46 may be thrown out of gear at any time. as for instance, when thedigging and scoop loading-drum B would otherwise be operated in anundesired reverse direction.

By the gearing above described, it will be understood that traction maybe imparted to the main truck wheels a for transportation of theapparatus, in which case the removing drum may be elevated away fromcontact by its lifting .mechanism 14. etc., and that when located inposition for operation with the removing orloading drum lowered, thetraction gearing is inactive. the power of the motor being then utilizedto drive the conveyor and removing drum together.

It will, of course, be understood that a gas engine or other prime movermay be substituted for the electric motor -15 shown in the drawings andthat the invention is in no Way restricted to the particular kind ofmotor utilized. Guiding mechanism for wheels 5 of any suitable kind maybe used, as knuckles 5e connected with a cross rod actuated by lever 56and gearing 57 provided with a hand wheel 58 generally similar to thatutilized in clutch mechanism.

The construction and operation of the invention will be readilyunderstood and appreciated from the foregoing description. Mounted uponthe main supporting frame as it is, the machine may be transported underits own power over any suitable surface, and located in position tooperate upon a pile of loose material C, as for instance, sand, coal, orthe like. Drum B having been adjusted and conveyor A raised to thedesired inclination, as for instance, sufficiently high to deliver intoa receiving wagon. mine car, or the like, gearing 39, 4.0 and i2 willtransmit driving movement simultaneously to the drum and conveyor, sothat the drum, in its rotation, will scoop up segregated quantities ofthe loose material of the pile and will deliver them o to the receivingend of the conveyor, which will then carry the material outwardly in theusual way, and deliver it over the terminal drum 2? by gravity.

The apparatus is very compact, comparatively simple in construction andoperation. light and portable, and inexpensive to build and maintain. Itis capable of being used in many lo aitions where it can be substitutedfor manual handling of the loose material, as in quarries, mines, orelsewhere, and is well adapted to perform its intended functions in ahighly satisfactory manner.

The invention may be variously changed or modified by the skilledmechanic in various details or otherwise, but all such changes are to beconsidered as within the scope of the following claims.
